Latest Patents

One of Kanayama's latest patents is for a steel pipe that boasts high ductility and high strength, along with a unique production process. This steel pipe features a structure primarily composed of ferrite or a combination of ferrite with pearlite or cementite. It is characterized by a grain size not exceeding 3 µm, with an elongation greater than 20%. The tensile strength and elongation product is greater than 10,000, and it exhibits a percent ductile fracture greater than 95%, ideally reaching 100%, as measured by the Charpy impact test at -100 °C. The composition of this steel pipe includes C: 0.005-0.03%, Si: 0.01-3.0%, Mn: 0.01-2.0%, and Al: 0.001-0.10% by weight. The production process involves heating the steel pipe stock to a temperature of (Ac,+50 °C) to 400 °C and reducing the diameter by more than 20% during rolling. This innovative approach results in a steel pipe with superior toughness and resistance to stress corrosion cracking.

Another notable patent is for an ultrafine-grain steel pipe that contains fine ferrite crystal grains. This steel pipe is designed to offer excellent toughness, ductility, and a favorable ductility-strength balance, along with superior collision impact resistance. The production method involves heating a base steel pipe with ferrite grains and applying a reduction process at specific temperature ranges, ensuring the resulting product meets the desired specifications.
